Irisin (Ir), a recently identified adipomyokine, cleaved and secreted to the circulation from the FNDC5 protein in response to physical activity and some environmental conditions has been postulated to induces the differentiation of a subset of white adipocytes into brown fat and mediates the beneficial effects of exercise on metabolic homeostasis. Polycystic ovary syndrome (PCOS) – one of the most frequent endocrinopathies affecting women of child-bearing age is associat...

Brown adipose tissue metabolism is of remarkable pathophysiological interest, because it could be a target for future therapies for obesity and metabolic syndrome. Irisin (Ir), recently identified novel adipomyokine is essential in a white-to-brown fatty tissue transdifferentiation, and mediates some of the positive influences on metabolic disorders through increase of energy expenditure. The exact regulation of Ir secretion and action is unknown but significant positive assoc...

We report the case of 57-year-old man with end-stage renal disease, primary hyperparathyroidism and after an surgery of upper parathyroid glands with ectopic parathyroid localized in lung. Patient was directed to our hospital to perform diagnostics on hyperparathyroidism. Two years earlier (2011) patient was hospitalized because of weakness and weight loss, and was diagnosed with primary hyperparathyroidism. In 2012 he underwent the bilateral parathyroidectomy of upper glands ...

Polycystic ovary syndrome (PCOS) is a common endocrine abnormality connected not only with reproductive problems but also with impaired energy homeostasis leading to metabolic disorders including metabolic syndrome. Irisin (Ir), recently identified novel myokine, has been proposed to mediate some of the positive influence on metabolic disorders. The aim of our study was to search the relationship between Ir plasma concentration in PCOS in the context of metabolic disturbances....

Results of metabolomic studies showed the relation of branched-chain amino acids (BCAA) and aromatic amino acids (AAA) with metabolic disorders.Basing on this observation we assessed amino acid profile in 286 professionally active men (aged 36–60 years). 141 of them met the criteria of metabolic syndrome (MS) and remaining 142 served as controls.Quantitative analysis of BCAA (leucine-LEU, valine-VAL, isoleucine- ILE) and AAA (...
